Specification of Letters Patent.

Patented Apr. 28, 1914.

Application filed August 22, 1911. Serial No. 645,444.

To all whom "it may concern:

Be it known that I, Mounts Sononxrnrn, a citizen of the United States, residing at Mariabergstrasse, Rorschach, Switzerland, have invented new and useful Improvements in Machines for Cutting Embroideries; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac companying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to a machine for cutting off strips from embroideries along the embroidery edge. According to this invention the strip after being cut ofi is guided through a slot in a direction which differs from that in which the main part is led off. The slot is formed by an adjustable stop and a guide fixed to the stop. To obtain an accurate cut the stop is provided with an edged collar corresponding to the form of the knife. The fabric is conveyed by means which may at the same time exert a stretching action on the fabric. The conveying means ma be formed by rolls for instance, the peripheral speed of which increases in the direction in which the fabric moves, the rolls being arranged so as to suit the unevenness of the fabric. The latter is led by an axially displaceable roll to the cutting place, a brake being provided for this roll. After the cutting is performed the main part of the fabric is also guided by a roll. A ledge is arranged above the axially displaceable roll so that it causes the fabric to be guided and to move along an embroidery edge. The part of the fabric which is cut off is drawn by suitable means and guided by a device preferably consisting of a conical drum, the direction of the axis of which is adjustable.

A construction according to this invention is illustrated in the accompanying drawings in which Figure 1 shows the machine in elevation, Figs. 2 and 3 show a plan view of the same, the upper parts of the machine being omitted in Fig. 3. Fig. 3 is a partial section on line DD of Fig. 3, Fig. a is a section on line A-A of Fig. 2, Fig. 5 is a partial section through one of the rolls conveying the fabric, Fig. 6 is a section on line EE of Fig. 3, Fig. 7 illustrates the working of the machine, Fig. 8 is a section on line BB and Fig. 9 on line C G of Fig. 7.

A support 2, representing a table 2 in its nnddle part, and a fork-shaped bracket 3 are fixed to the standard 1. A vertical shaft 5 is mounted in bearings 4: and L at the end of the bracket 3. The lower end of the shaft carries a plate-shaped knife 9. A rope pulley 6 being mounted on the shaft 5 between the bearings 4 and 4 is impelled from any source of energy, by means of an electric motor 33 and a rope pulley 31 for instance. The shaft 5 is fixable in axial direction by adjusting nuts 7 (Fig. 1) and a collar 8 (Fig. 4). A bell-shaped guard 10 which surrounds the knife 9 is screwed to the bearing 4 and provided with an opening 11 on that place on which the fabric is out. (Fig. 2.) Guides 12 and 12 by which an adjustable stop 13 is guided are fixed on the surface of the table 2. This step can be moved to and fro in the direction to the knife by means of a screw 14: which is guided in a projection 2 of the table 2* and which engages threads in the stop 13. The stop is provided with a circular conical cut 13 which exactly suits th circumference of the knife 9. The stop possesses an edged collar 13 which follows the upper edge of the cut 13.

A guide 15 is fixed to the stop 13 by means of a ledge 13. A small slot through which the separated strip of fabric passes is formed between the outer surface of the guide 15 and the inner surface of the stop 13. The upper circular edge of the collar 13 is arranged so-mewhat higher than the edge of the knife 9, while the guide 15 is located below the knife 9. A suitably shaped leaf 15 is secured to the guide so that the fabric can easily be brought in the slot formed by the stop 13 atone side and by the knife 9 and the guide 15 at the other side. This slot is of so small a width that only the embroidery background and not the embroidery can pass through it. The table 2 is covered by a thin plate 16 producing thus a plain support for the fabric.

Rolls 17, 18, 19 and 20 mounted over the plate 16 of the table 2 convey the fabric to be cut. The axles 17, 18, 19 and 20 of the rolls are rotatably supported by parts 21 elastically mounted in a fork 21 which is f; stoned to the bracket 3 (iiig. 1). Thus th olls "re adapted to suit the unevenness be impelled by l for instance by means of the the sl oi": the motor and a ino rated on a vertical shaft. is rotatably supported by the .nd a projection i3 of the fork a bevel gear Wheel.

Since the axis of the cone can he brought in every desired dircctioin a strip oi? any desired Width can be carried away in a stretched condition. it is of importance therefor that the separated strip and the main part of the fabric are led away in dilierent directions. in some :ases it ill means the roll 17 may be posiii ely lLlpolled, lorinmgg' thus a conrcyiinig device while the other rol s 20 act as a stretchinn device.

Any suitable device may be used 1 of the stretching device as described above. For instance the table supporting the fabric may be omitted and the latter carried by a conveyer band. The fabric may be led to the band by suitably arranged conveyer rolls whereby the band is impelled at a higher speed than the rolls. The fabric is pressed against the conveyer bands by suitable independent elements, which may be formed by rolls for instance that are movable in the direction rectangular to their axis.
